HelioSeal ™ Delivers Twice the Capacity Using One-Quarter Less Power

One-third more capacity and 23% lower energy consumption. Available today. That's the power of helium. Delivering the industry's leading capacity at 8TB, Ultrastar He 8 is based on the widely accepted and proven HelioSeal™ platform. HelioSeal technology replaces air with helium inside the drive, reducing air turbulence and enabling 7Stac™, a seven-disk design in a traditional 3.5-inch form factor. Ultrastar He 8 goes beyond what any air-based HDD can do and seamlessly integrates into virtually any mainstream enterprise environment. Cooler and quieter with industry-leading power efficiency (Watts/TB) and no-compromise performance, the Ultrastar He 8 lays the foundation for future growth in massive scale-out environments.

We recognize the growing pressures that data centers face. Volume is expanding, operating costs are rising while budgets remain flat. Lowering the total cost of ownership (TCO) has become the focus of data center architects. Ultrastar He 8 provides the best TCO value proposition and delivers greater storage efficiency with breakthroughs in capacity, power efficiency and best-in-class performance. This latest HelioSeal hard drive achieves up to 3X higher random write performance than the prior generation , Ultrastar He 6 , thanks to HGST media cache architecture, a disk-based caching technology. He 8 offers a 12Gb/s SAS (6Gb/s SATA) interface for easy integration into high performance data centers. New features like Rebuild Assist dramatically reduce RAID rebuild times and maintain system performance during the rebuild process. Learn more in our Rebuild Assist technical brief.
